DATA CENTRE SOLUTIONS

Having worked with data centres for over 15 years we know it is critical for your operations and consumer trust that you have a resilient and safe electrical power system. We have and we will continue to support growth, assist in expansion and provide technical solutions to ensure that your data centre electrical infrastructure is reliable, future-proofed and operates within its designed parameters.

WHAT WE DOCASE STUDIES

SERVING THE DATA CENTRE SECTOR SINCE 2001

Since 2001, we have been advising our customers on how best to manage their electrical systems to meet the demands of the processes it supplies. Working together, our engineers can integrate into your organisation and develop solutions to solve your most technical needs. We strive to deliver Reliability, Efficiency and Safety to our clients in a cost effective manner. By including us from the design stage of your data centre we can advise on a system that can deliver the best outcomes for you now and long into the future.

DATA CENTRE INDUSTRY

POWER MONITORING SYSTEMS

We work with you to identify the best power monitoring systems for your facility. We commission and verify energy and power systems for compliance with EN 16247-1 for energy audits.

PROTECTIVE DEVICE COORDINATION

Isolating faulty components in a power system will help prevent serious power faults. We can analyse your electrical system, design overload protection, earth fault protection, distance protection and back-up protection to prevent these faults.

POWER FACTOR CORRECTION

Load power factor has a significant effect on losses by equipment and electrical network. It can be improved by the design and installation of local or plant wide power factor correction solutions.

RISK ASSESSMENT

Legislation imposes a duty on every employer to identify hazards in the workplace and assess the risks to employees who may be exposed. We can work with you to identify these risks and develop safety procedures.

HARMONIC FILTERS

Power quality problems can contribute to higher energy costs, slower production and faults in your electrical system. Proactively addressing these issues from design stage can offer significant reliability and cost benefits.

ELECTRICAL DESIGN

We provide a one-stop shop for electrical design services that include feasibility studies, concept design and pricing through to construction management, and commissioning.

EARTHING STUDIES

Earthing systems also assist in the operation of overcurrent devices during fault conditions. A functioning and well maintained earthing system is essential for the safe operation of electrical systems.

ARC FLASH

We can carry out risk assessments and identify preventative measures necessary to protect workers, electrical infrastructure and processes against arc flash incidents.

Solving Harmonic issues with Schaffner Active Filters
The Challenge

Power quality analysis carried out by Premium Power identified harmonic issues for one of our pharmaceutical clients, based in Ireland.
Our client experienced variable frequency drives failures and was concerned about a significant reduction to the lifespan of other electrical equipment onsite, as well as issues complying with the European Standard IEC61000-2-4.
Our solution was to install Schaffner Active Harmonic Filter in eight different locations across the site.

The Solution

Since the deployment of the units, a significant reduction in the voltage harmonics has been measured, assuring that the Voltage Total Harmonic Distortion is less than 5%, as required by the aforementioned standard.
Furthermore, thanks to the Schaffner active harmonic filter capability to target individual current harmonics, these have drastically been reduced and the client will not have increased costs due to the lifespan of their electrical equipment being shortened.

Arc Flash

Arc Flash Study Using NEN3140 Standard
The Challenge

One of our Data Centre clients in Ireland needed to get an Arc Flash Study done at their Netherlands plant. This was quite a large site with almost 300 boards to be assessed.
A careful evaluation of current onsite documentation was required to ensure there were no gaps when building the model.
Our engineers carried out a full survey of the electrical infrastructure including MV/LV equipment, power transformers, backup generators, motors, cables, and protection equipment.

The Solution

We built a model from this information using SKM software. Once complete we were able to calculate the arc flash values in Cal/cm2 for every point in the network according to NEN3140. This identified all the high-energy areas that were at risk of arc flash.
We were able to bring all onsite arc flash levels to below 8 Cals/cm2 through protection coordination setting changes and recommended certain hardware changes. Our suggested changes were implemented resulting in a safer working environment. We also recommended the wearing of non-intrusive arc flash PPE for electrical workers.

Voltage Study for Large Data Centre
The Challenge

A client noticed some unusual operational issues that were cause for concern, specifically with their backup generators transfer sequence in the event of utility parameter variations. They had also observed that the predefined equipment set thresholds were also contributing to these undesirable operational issues at the site. Unresolved, this had the potential to impact the reliability of the system and increase downtime which for this particular client would result in losses of millions. Being such a big energy user, it also raised concerns with TSO because the fluctuations they were experiencing were having a knock-on effect on the wider grid.

The Solution

After much deliberation, our power quality team developed a strategy that required the gathering of load data from the site in real-time and inputting this into a model. The model would then be subjected to a range of different over and undervoltage conditions, switching scenarios etc, the aim being to simulate the behaviour and static response of the data centre to identify what was causing the issues. The results of the simulations were then compared with the values seen on site and the model was adjusted to reflect the real behaviour of the system. This is extremely difficult to do and not common practice, but we were able to achieve an error margin of approximately 0.25%.

Grid Connection Study for Battery Energy Storage System
The Challenge

Recently, we performed a grid connection study for one of our large data center clients who was looking to install a Battery Energy Storage System (BESS) on their site.
The goal of the study was to examine whether the data center would still be grid compliant after the addition of the proposed BESS. Due to their size this site is a large consumer of power, any changes to their mode of operation sparks a keen interest from the local utility provider to ensure it does not adversely affect the local grid.

The Solution

Using the DigSilent modelling tool we evaluated the various modes of operation made possible by the BESS and how the power supply reacted to different operational scenarios as set out by the utility. Frequency response, reactive and active power response, and fault ride-through capability were all evaluated.
We concluded that the addition of a BESS at this particular site would not impact the client's ability to comply with grid requirements. The utility provider was satisfied with the results and the client can now confidently proceed with their plans to install the BESS.
